Definitions

  • This invention refers to a gathering and pleating device for flexible tubular containers.
  • the field is that of machines that pack products such as pieces of fruit and similar into cylindrical mesh bags with a tubular-shaped reticulated structure.
  • all these devices comprise a pair of pincers that hold the container by its upper mouth in an open position while the container is being filled. After filling, the container is closed by bringing together the holding pincers and subsequently joining the (two) facing sides that form the mouth, and they come into contact by the action of some welding clamps or other similar mechanism.
  • the sealing devices in question present a series of functional and formal drawbacks.
  • the threads or tapes that form the meshes of the container usually are subjected to excess tautness that causes imperfections, and the meshes even break when the containers are manipulated once they are filled.
  • the device to be described eliminates the above mentioned drawbacks and provides a practical, reliable system for the proposed purpose.
  • a plate 2 functioning as a frame, has an inverted and modified Y shape, with a symmetrical configuration with respect to a central vertical plane, provided with functional perforations ( figure 2 ), and supporting, with a symmetrical arrangement with respect to the central vertical shaft of the device, the following elements:
  • the component elements of the described device make the movements indicated in figures 7 to 12 .
  • the central pieces 10, 10' and the exterior pieces 15, 15', 16, 16' are located on the outside of the mesh tube 17 and the centering pieces 11, 11', 12, 12' and the fixed pieces 13, 13', 14, 14' on the inside ( figure 7 ).
  • the interior sheet metal pieces are located on the apexes of the mouth and the exterior pieces approach and are inserted into lateral recesses of the tubular section ( figure 8 ).
  • the adjustment wheels 9 and 21 are used to regulate the precise working positions and movements of the sheet metal pieces.
  • the mouth of the tubular mesh section 17 is permanently closed by means of a weld made while it is kept pleated and gathered.
  • the sheet metal pieces occupy the final positions indicated in figure 9 .
  • the device thus described permits the gathering and pleating of the open ends or mouths of a mesh bag obtained by cutting a continuous mesh tube into pieces of equal length.
  • a mesh bag obtained by cutting a continuous mesh tube into pieces of equal length.
  • some are introduced, in a linear downward movement, into the inside of the flexible tubular section (of mesh) through its open mouth, whereas the rest of the device pieces remain on the exterior of the tubular section's perimeter.
  • the sheet metal pieces make some revolving movements around two symmetrically placed rotating shafts in order to make a series of pleats in the mesh walls of the tubular section and, at the same time, gather it together.
  • the sheet metal pieces move upward in a linear movement so that the mouth can be closed by the corresponding device of the packing machine.
  • the pneumatic cylinder 5 produces a linear downward movement of the sheet metal pieces with respect to the mouth of the mesh tube 17; the central sheet metal pieces 10, 10' remain on the outside, the centering pieces 11, 11', 12, 12' on the inside, the fixed sheet metal pieces 13, 13', 14, 14' on the inside, and the exterior sheet metal pieces 15, 15', 16, 16' on the outside.
  • the exterior bands of a weldable material are fastened to the tubular mesh element before making the cut to form each individual bag.
  • the bands in question serve as a support for the brand, the packaged product specifications and other information.
  • the handle of each bag is attached after the bag is filled with the product and at the moment when the upper mouth of the bag is sealed.
  • Another device will close the lower end and, once the packing machine has conventionally proceeded to fill the bags, their mouths are gathered and pleated and subsequently sealed.
